Abstract In this study, a patch removing based Isogeometric analysis (PR-IGA)
method is proposed to conduct the holed structural analysis with only one parametric domain, in which there are also no trimmed elements. The theoretical foundation of this novel patch removing approach is that any holed structure can be
obtained by removing sub-patches (i.e., the holes) from an intact base patch. Since
the parametric domains of these patches are all meshed by rectangular grids, the
elements in the resulted holed structural parametric domain could all be
untrimmed rectangles under certain mapping conditions. To achieve the special… More >
